Task 2

Task 1: Steering control decision made (see task 1)

Task2: Diagramming the circuitry and control needs

Hey Team, let’s get started on the next task. I think this can be a lot of fun and a great learning experience, as well as a cool way to meet people from around the world who share the same passions. So next up:

You are right, changing direction via controlling fan is not an efficient way. Here is another idea why don’t we use blades parallel to fans, which will be rotatable along vertical axis so that we can produce a thrust vector like in hovercraft. And use a caster wheel in front so that there will be less hindrance while turning car. #idea#brainstorming

It will be not as efficient because if speed of F1 is decreased than F2 in order to turn then the radius of curvature while turning i.e. turning radius will be large so wont be able to make sharp turns.
plus if front tires are not turn-able(unlike in ackerman mechanism) as mentioned in above pic, then more force will be required due to friction b/w tires and floor, as a result more differential pressure will be required cause delay in turning consequently large turning radius.
That’s my understanding.

If you’re going to user an ultrasonic sensor module, you really want this thing to turn as tightly as possible other wise the car is going to be doing a lot more of backing up turning backing up turning backing up turning instead of driving forward
